.SH "NAME"
ccnls \- Attempts to list name components available at the next level of the hierarchy for a given CCNx name prefix\&.
.SH "SYNOPSIS"
.sp
\fBccnls\fR \fIccnxname\fR
.SH "DESCRIPTION"
.sp
The \fBccnls\fR utility lists name components available after the supplied CCNx name prefix, \fIccnxname\fR, for content objects that are cached in the local \fBccnd\fR\&.
.sp
This utility does not have explicit flags or options, but can be modified via environment variables\&. These include the scope of the generated interest (\fICCN_SCOPE\fR), the amount of time to wait between responses from \fBccnd\fR (\fICCN_LINGER\fR) and whether signature verification is desired (\fICCN_VERIFY\fR)\&.
.SH "OPTIONS"
.sp
The \fBccnls\fR utility does not have additional flags or options\&. Behavior can be changed by using the following two environment variables\&.
.sp
.if n \{\
.RS 4
.\}
.nf
CCN_SCOPE=
  Scope in generated interests (0, 1, 2)\&. The default is none specified\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
CCN_LINGER=
  Timeout for not receiving data\&.  The default is 0\&.5 seconds\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
CCN_VERIFY=
  If set and non\-empty, indicates that signature verification is required\&.
.fi
.if n \{\
.RE
.\}
.SH "EXIT STATUS"
